By using the CAISO API you are agreeing to the terms and conditions contained below (“Terms”). Your license to use the CAISO API is conditioned upon your agreement and conformant with the Terms. We reserve the right to update and otherwise amend the Terms from time to time without notice.
License grant. CAISO hereby grants you a revocable, non-exclusive, non-sublicenseable, non-transferable, limited license to use the CAISO API solely in accordance with the Terms. Your license is automatically revoked if (i) you violate any of the Terms, (ii) we send a written notice of termination to you, or (iii) we disable your use of the CAISO API.
Adverse and Excessive Use. You may not use the CAISO API in a manner that adversely impacts CAISO’s systems, including but not limited to CAISO’s servers or other applications. Further we reserve the right to suspend, or terminate your use of the CAISO API in the event your use is deemed excessive by CAISO.
Monitoring. You may not use or access the CAISO API for purposes of monitoring the availability, performance or functionality of any of CAISO’s systems or services or for any other benchmarking or competitive purposes.
Third Party Access. You may provide access to the CAISO API to third party developers (e.g. agencies or partners). You are responsible for ensuring that any third party to whom you provide access abides by the Terms. Further, CAISO reserves the right to reject third party access to the CAISO API.
Disclaimer of Warranty
The CAISO API is provided “as is” and CAISO disclaims all warranties, conditions, or representations (express, implied, oral or written) with respect to the CAISO API and any support related thereto, including all warranties of merchantability, compatibility, fitness for a particular purpose, non-infringement, non-interference, accuracy of data, and warranties arising from a course of dealing.
Limitation of Liability
The following limitations of liability apply irrespective of any failure of essential purpose of any limited remedy, and also apply regardless of the legal or equitable theory on which damages are sought.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, TORT, CONTRACT, OR OTHERWISE, SHALL CAISO BE LIABLE TO YOU OR ANY OTHER PERSON FOR ANY MONEY DAMAGES, WHETHER DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL, INCLUDING, BUT NOT LIMITED TO, LOST PROFITS, LOSS OF EARNINGS OR REVENUE, LOSS OF USE, LOSS OF CONTRACT OR LOSS OF GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THE USE OF THE CAISO API OR CAISO DATA, EVEN IF CAISO SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY ANY OTHER PARTY, AND REGARDLESS OF THE FORM OF ACTION (WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), PRODUCT LIABILITY OR OTHERWISE).
Release and Waiver
To the maximum extent permitted by applicable law, you hereby release and waive all claims against CAISO, and its, officers, agents, licensors, and employees from any and all liability for claims, damages (actual and/or consequential), costs and expenses (including litigation costs and attorneys’ fees) of every kind and nature, arising from or in any way related to your use of the CAISO API. If you are a California resident, you waive your rights under California Civil Code 1542, which states, “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.” You understand that any fact relating to any matter covered by this release may be found to be other than now believed to be true and you accept and assume the risk of such possible differences in fact. In addition, you expressly waive and relinquish any and all rights and benefits which you may have under any other state or federal statute or common law principle of similar effect, to the fullest extent permitted by law.
Hold Harmless and Indemnity
To the maximum extent permitted by applicable law, you agree to hold harmless and indemnify CAISO and its officers, agents, licensors, employees and agents from and against any third party claim arising from or in any way related to your use of the CAISO API, including any liability or expense arising from all claims, losses, damages (actual and/or consequential), suits, judgments, litigation costs and attorneys’ fees, of every kind and nature. CAISO will use good faith efforts to provide you with prompt written notice of such claim, suit or action.
Modifications to CAISO API
CAISO will occasionally make changes to its API, including backwards incompatible changes. Accordingly, you should consider registering at
to access API specifications and scheduled modifications. Also, parts of the CAISO API are undocumented, including certain methods, events, and properties. Given that these undocumented aspects of the CAISO API may change at any time, you should not rely on their behaviors.
The Terms are governed by the laws of the State of California (excluding any rule or principle that would refer to and apply the substantive law of another state or jurisdiction). Further, you and CAISO agree that any claim or cause of action under or relating to the Terms must be brought in the state or federal courts located in Sacramento, California and you agree to submit to the exclusive personal jurisdiction of such courts. The Terms constitute the entire agreement between the parties regarding the subject matter stated herein, and supersedes all previous communications, representations, understandings, and agreements, either oral, electronic, or written. If any provision of the Terms, or the application thereof, is for any reason and to any extent determined by a court of competent jurisdiction to be invalid or unenforceable under applicable law, a valid provision that most closely matches the intent of the original will be substituted and the remaining provisions of the Terms will be interpreted so as best to reasonably affect its original intent.
